Kyle, I checked some of those suppliers and didn't see it either. A call to Badger should help. It's possible the Base may be special order. Farrell is supposed to be good kit too.
Does your scope have limited movement that you need to stay with the zero cant? If not, maybe the tapered base will work fine.

I have a Nightforce 5.5-22x56mm scope and the rings I have...Badger not sure of hieght.....will not have much clearance. They came with the scope and clearance will be tight. I was thinking with the cant, it will point the scope down, reducing clearance more???

Thought if I get a no cant there would be a bit of clearance...do not know. I will measure them tonight and see what height they are.
